Render and playback settings
 Filters: If this option is not selected, all filters are ignored during playback, improving
real-time performance.
 Frame Blending for Speed: If this option is selected, clips with speed adjustments are
processed with frame blending. Frame blending makes slow-motion video smoother
by synthesizing in-between frames. This requires more processing power, so you can
turn it off when you are working on a rough cut.
 Motion Blur: If this option is not selected, motion blur is ignored for all clips in your
sequence.
Render settings
 Frame Rate: You can use this pop-up menu to reduce the frame rate of rendered
segments of a sequence, dramatically speeding up rendering but lowering playback
quality. For example, if you’re editing at 29.97 fps, and you choose 50 percent in the
Frame Rate pop-up menu, rendered effects in your sequence play back at 15 frames
per second.
 Resolution: Choose a percentage from this pop-up menu to reduce the resolution of
rendered effects, speeding up rendering but lowering playback quality. For example,
if you’re editing with a frame size of 720 x 480, choosing 50 percent lowers the
resolution of rendered effects to a noninterlaced 360 x 240. Rendered effects are still
full-frame, but they have lower resolution.

Tip: You can control many of these settings by assigning keyboard shortcuts or
adding buttons to the button bar using the Keyboard Layout window. For more
information on using the Keyboard Layout window, see Volume I, Chapter 10,
“Customizing the Interface.”
